Abstract
A ribbon-free solar cell module and a method for preparing the same are provided. The solar cell module is in a five-layer structure, including a first layer of conductive back plate, a second layer of conductive adhesive connection joints, a third layer of back contact cells, a fourth layer of packaging material, and a fifth layer of tempered glass which are successively laminated together, wherein the first layer of conductive back plate is in a novel laminated structure. Such a design provides a ribbon-free solar cell module and a method for preparing the same which are low in cost, and easy to implement.
Claims8
A ribbon-free solar cell module, comprising a first layer of conductive back plate, a second layer of conductive adhesive connection joints, a third layer of back contact cells, a fourth layer of packaging material, and a fifth layer of tempered glass which are successively laminated together, wherein the first layer of conductive back plate employs a back plate layer one of fluoropolymer, a back plate layer two of PET material, a back plate layer three of metal circuit and a back plate layer four of sealing material which are successively laminated together.
A method for preparing a ribbon-free solar cell module, comprising the following steps:
- (a) printing conductive glue on a first layer of conductive back plate by dispensing or stencil printing, positions for printing conductive adhesive being matched with electrode point positions of a third layer of back contact cells to form a second layer of conductive adhesive connection joints;
- (b) placing the third layer of back contact cells accurately on the second layer of conductive adhesive connection joints to ensure that the electrode points of the third layer of back contact points correspond one-to-one with positions of the second layer of conductive adhesive connection joints;
- and
- (c) laying a fourth layer of packaging material and a fifth layer of tempered glass on the third layer of back contact cells.
